To all whom it may concern:

Be it knownthat I, Lns'rnn L. Gunman, a citizen of the United States,residing at Natick, in, the county of Middlesex and State ofMassachusetts, have invented cererating upon the heels of boots orshoes. In

the following specification and accompanying drawings the invention isdescribed and illustrated as embodied in a machine for attaching heelsto shoes, but it should be understood that this is for the purpose ofillustration, and should not be construed as a limitation of'the scopeof the invention.

In performing operations upon the heelsof shoes, such, for example, asheel attaching, top lift spanking, at; the work is usuallysupported'upon a jack or equivalent dei'ice. It is a common 'practice tosupport; a shoe upon a last mounted upon a Jack and to effect relativemovement-between the jack and a corresponding pressing member, such as anailing die, to compress'and hold the solwork whilea tool operates uponit, it may. be to drive heel attaching nails there through. Thethickness and density of the stock used in shoe soles vary considerably,

- and the density and heightof heels are subject to very wide variation.The height of wood lasts, upon which welt shoes are usually heeled, 'isalso a very uncertain fart-- tor, whichmust 'be taken into considerationin positioning the work pressingand'hold- 40 mg members and it hasalways been a serious problem with inventors and designers of heelingmachinery for use witlrwood lasts to provide mechanism forcompensating'for the varying thickness of the work and last in such away as to insure the, application p of a uniform and sulficient pressure.to'the work whlle avoiding danger of breaking or crushing the last byexcessive: pressure.

The'aim of the present invention" is to 00 provide a machine which willoperate rapi'dly'iandturn out high grade, uniform work 7 under thediffering conditions above men *tiond, withw'a minimum of labor and]skill upon the part of the operative. To this end an important featureof the invention nnnnme-nacmnn;

resides in the provision in a machine having; a shoe support and acooperating pressing member, such as a nalling die, of means for:

automatically effecting relative approaching" movement of the shoesupport and die,

whereby those members are preliminarily g POSltlOIlBCl 1n contact withthe work "a-dis-f 1 tance apart dependent upon the thickness jOf.

the work and means for them eflecting further predetermined relativemovement-orig} the membersmentioned, for the purpose of-gfl' giving thework a uniformamount of com- 'pression.- Preferably the initial approachmg movement, or'me'asuring, is effected by},

spring operated mechanism, whereby a defi- 7'9 nite, substantiallyuniform measuring pres- 5 vsure 1S brought to'bear upon the workirrespective of its thickness and without regardi to the care or skillexercised by the operm tive;.and a predetermined amoun't'ofaddie 7 5-tional approaching movement is then efi'ected by power'mechanism tocompress'the work.

In the specific machine hereinafter described I have shownthe mechanismfor effecting the last mentioned movement as embodied '80" in poweroperated means for moving the nailing (lie toward the j ack, but'itshould' be understood that it is within the invention to move eitheror both of said members. v

, While it is preferable thatthe above men tioned operations be effectedautomatically v by the simplest possible mechanism, it is desirable thatthey be separately under the control of the operator so that he mayinespect the work after it has been located and measured and before it hasbeenoperate d upon. A further feature of the invention accordinglyconsists in the proiision ,of a single manually operated device forcontrolling, first the operation of the automatic measuring mechanism,and then the -.operavtion of the power operated pressure applyingmechanism. This device may comprise a tread]ewhich. upon beingdepressed, releases 'the spring means for actuating the measuringmechanism. after which r nner movement of the ,treadle starts the, powermechanism of the machine.

motion. .This featuwolf l importance because it ms t tomatically andconsequently uniformly. It

- -also prevents the operator from subjecting the work to an excessivemeasuring pressure as has sometimes happened in those machines where themeasuring is effected manually.

In the preferred form of my invention means is provided for preventingthe shoe support from yielding under the heavy pressiure exerted uponthe work by the nailing 1e. sisting of a plurality of interdigitallyarranged wedges placed in the connection -which transmits measuring{movement from the spring or springsto the shoe support. The wedges, inaddition to transmitting movement to the shoe support, act as lockingmeans, .preventing the 'shoesupport from yielding under pressure.

A further'feature of the invention resides in the provision of positiveconnections between the mechanism which supplies the power forcompressing the work and the work engaging member-moved by'it, said.positive connections being capable of such adjustment that a "variationin the amount of movement of the work engaging member may be securedwhile the movement of the power actuating mechanism isalways the same.Ina satisfactory construction for effecting this result the. connectionsabove referred to include a toggle and a connecting link forstraightening and breakmg the toggle, the connecting link beingadjustable in away to illustrate details of construction.

length so that the amount by which the toggle is broken may be'variedand consequently the amount ofmovement effected by it may be controlled.4

Further features of the invention have relation to the improvement ofthe controlling means for the movements of the heel and toplift holderand various details of mechanism for actuating the work support andnailing die;

The preferred embodiment of the invention is illustrated in theaccompanying drawings, in which,

Fig.

last which: is secured to the lowerend of the swinging jack 12. The jackis pivoted .at its upper end to an adjustable j ack-carrier 13 carriedat the lower end of a vertically- -sliding plunger 14. By means of anadjusting screw 16, turned by a hand-wheel 17,

the plunger is connected with a universal joint 18 at the forward end ofthe walkingbeam 19, which is pivoted at 21 on the frame of the machinein the usual manner. To the other end of the walking-beam is pivoted theupper end of'a rod 22 by which the position ofthe walking-beam, and thusthe vertical positionjof the jack, iscontrolled.

The means for actuating the rod 22 constitute a'novel feature of thepresent inventionJ- The lower end of this rod is fixed in a block 23which slides vertically in a bracket 24 fixed to the frame of themachine. On the lower surface of this block is'a dovetailed guide-wayengaging a correspondingly-formed projection on 'a wedge 25.

nat'ed as 25, 26, 27, and 28 respectively, each of these wedges beingslidingly connected with those above and below by means oftongueand-groove projections and recesses as shown particularly in-Figs. 3 and 4; and the lowermost wedge 28 has also a tongueand-groovesliding connection with a guide 29.fixed upon the bracket 24. As shownin 6,- the arrangement of the wedges is uch that if the wedges 25 and 27be moved 0 the left, and the wedges 26 and 28' be moved simultaneouslyto the right, the block -The wedge 25 is the uppermost ofa series offour oppositely-disposed wedges, desig 23 and the rod 22 will be raised,while, upon 1 an opposite movement of the wedges, the blockand the rodwillbe drawn downward positively, owing to the tongue-and-grooveconnections between the wedges. To actuate the wedges as just described,each wedge has a rack formed upon its rear surface, andv these racks areso arranged that those on the wedges 25 and 27 are engaged by a verticalpinion 31, while those on the other two wedges are engaged by a verticalpinion 32. These pinions are loosely journaled upgn studs mounted in thebracket 24. e pinions are actuated by means of a rack 33,

which is located between their lower portions and. has teeth engagingboth pimons, as

shown-in Fig. 7, so that when the rack is moved longitudinally thepinions are rotated simultaneously in opposite directions.

"The rack 33' is actuated in-one direction by springs 34, of which therear ends are attached' to a pivot-pin35 mounted in the lugs on therack. The forward ends of these springs have adjustable connections 36'with the frame of the machine- When thefmeche anism just described isfree tooperate, the

springs draw'the rack forward, thereby r9 tating the pinions and movinthe wedges such a direction as to raise e 111: block 23 the rod 22;Through this session the.

walking-beam 19 is swung about its pivot,

thereby lowering the stem 14 of-the jack,

and this movement. continues until the heel s'eatpf the lasted shoe hasbeen brought into closeyengagement with "a heel held in the heel-holder,or, in the case of the operation of 'aifixing the top-lift, untiltheheel, which has previouslyjbeen-nailed to the shoe, has

been brought close tofthe top-lift; The

. mechanism thus automatically compensates for the varying height orthickness of the work, whatever it may be, and also applies a.zpredetermined substantially uniform amount of. pressure to the work"before the other parts ofthe machine operate to compress I and nail the'heel or to spank the-top -lift upon the heel,'.as the case may be. Inthis connectionthe adjusting-screw 16' is not essential andxmay beomitted, but it-is preferred, to retain this device, as it. permitsaj,preliminaryadjustmentby which the posi tion .o'f'th'e parts is roughlyapproximated'to the class of work upon which the machine is to operate,thereby relieving the automatic mechanism of unnecessary movement.- Theobject in employing a plurality of wedges in the mechanism justdescribed is to permit the use, in eachwedge, of a slight angler-ofinclination, 'whileat the same time securing the necessary amplitude ofmovement. By this arrangement the wedge mechanism .is renderedself-locking, so that although .itlis thrown into operation, to lowerthe jack, by

means of springs only,-it positively resists thetendency of'the jack toyield and rise when the compressing mechanism operates upon'the' work.

The wedge-mechanism is maintained in;

inoperative position, that is, in the position inwhich the jack israised, by means of 'a rod 37 pivoted at its rear end upon the pin 35011the rack33. This rod slides between upwardly-extending guides 38 mountedupon the pitman 39 by which the nailingmechanism-"is actuated. Betweenthe guides 38 is a 'detent-pi n A1 which normally engages a shoulder 42on the rod 37, thereby retaining the rod and the rack in rearwardposition in so andthus retalning the wedge mechanism in opposition tothe tension of the springs 34,

a jposition of-Fig. '6. After the operator has placed 1a lastedshoe-upon the jackin position to receive a heel, it is necessary torelease the wedge mechanismto perm t the-- shoe to engagethe heel,andthis is accom plished by means of the treadle employed, as is'commonin such machines, to control- 1 the operation of the nailing-mechanism,z

This treadle is pivoted at 41 011 the. frame of the machine, and it hasan upwardly extend l ing arm- 45 j which engages 'i the lower end of; an-arm {16- depending from a rock-shaft 4,7 jonrna-led-on the vpitrnan39.. A second arm 48 011 the rock-shaft is adapted to engage the forwardextremity 49 of the detent-rod 37, but the armf iB is normallyheld inlow er'ed position by a spring 51. With the parts in the, position shownin dbtted lines F ig.- 3, which is their normal position, .if thetreadle be slightly depressed, to the position shown in full lines insaid figure, the mechanism just described operates to raise thedetent-rod 37 as shown, thereby disengaging it from the detent-pin tlandallowing the springs 34 to move the rack 33 forward.

The nailing mechanism is controlled by the treadle43. To this endthetreadle has an upwardly-extending rearward extremity 52. WVhen thetreadle fully depressed this-extremity engagesan arm 53 on a rockshaft5a journaled in the frame of themachi-ne A"second arm 55, extendingupward from the rock-shaft, cooperates at its upper extremity with a lug56 on the driving clutch of the machine, which is of the wellknownHorton type. This clutch is emiployed to connect the driving shaft 58 0fthe machine intermittently with the fly wheel 57 by which the shaft isactuated, and to impart a single rotation to the shaft at each o'aeration of the clutch, in the usual manner. The arm 55 is normallyheld in engagement with the lug 56, so asto hold the the machine. Theupper arm is piyoted to the lower end of a slideblock 66 which-movesvertically in a guide 67 on the frame of the machine. This slide-blockis not connected directly with the nail-drivers, buthaslpro vision forlost motion, whereby it operates the nail-drivers only during the lastpart of its upward movement. To this end the block 66 is guided upon astem 68 which is fixed to, and projects downwardly from,the plunger 69by which the driver-block 72 is directly actuated. Thisplunger n oyesyer-- tically in the guide 67 and in an upper guide 71 also fixed on theframe of the machine.

Each of thesescrews has an eye formed at one-.endand-the.pivots 81 and 83. pass throughthe .eyesof the (screws? 82' and 82,respectively. "Upon, each turn buckle is rigidly secured a sprocket'wheel' 82 and an endless sprocket -chain'82 passes aroundathe ,twosprocketwheelsBQK-l 'Provision 'is thus made for controlling the amount"of compressing movement" .of the nailing-die. By adjusting: the "turnbuckles 82 the amount'bywhich thefltoggles79 are.

- broken may' be varied 'and,.consequently, the

amount of upward movement of the nailing. die maybe controlled, sinceequal forward. movements of a-pivot81 will produce difler-I ent amountsof upward movement' of the cross head 76 when said forwardfmovementsbegin at difl'erent points. The connection of the "turn buckles by thesprocket chain 82 insures that both turnbuckles will'rotate together andboth toggles will receive the vsame adjustment. Thus, although thepath-and amount of movement of the cam lever 84 and the pivot 83a'reinvariable, thef amount of upward movement of the" nailing die and,therefore, the amountof compression of the work may be varied betweenlimits determined only by the size and proportions of .the parts. Thetwo arms 88 are connected by a'bar 89, which ispivotally-mounted'concentric with the rock-shaft 54. From the bar 89 anarm 90 extends rearwardly and is pivoted to thelower end of a link 91.The upper end of this link is pivoted at 92 on the pitmanv 39.

- In the normal inoperative position 'of the machine the pitmanoccupiesthe position shown in 'Fig. 3, and at this time the cam-- levers84 arein such position that the links 82 are drawn rearwardly and the toggles7 9 are broken and the nailing-die lcjrwered. As soon as the drive-shaftis operated in. the

direction of the arrow in Figfl, thereby .raisingthepitman during thefirst 90- of 'such rotation, the mechanism above described operates todraw thecaml levers 84 downward, thereby causing the"*u-pper portionsoftheit}. cam slots to engage .the pins "86. Through this action theupper ends 01 the cam levers are thrown forward, thereby distancenecessary to compress the work to the required'extent. I During thisoperation the pitman is also moving forward so as to straightenthetoggle by which the naildrivers 'are actuated, but this movement isconnections above described. At this tune "the position ofthenail-drivers is determined by sleeves 78 dependingfrom a cross-head'7 7 in which the driver-block is mounted, this [cross-head being fixedon the upper end of the stem 69." 'These sleeves, at their lowerextremities, engage the cross-head 7 6, so that;

when the nailing-die rises to compress the;

work, as above described," the drivers are -raised with it, and thus thedrivers 72 are maintained in engagement with the nail holes in the die.During the latterv part of theforward movement of the pitman, after thecompressing operation has been vperformed, and afterthe lost motion hasbeen taken up in the toggle connections, the stem 69 is raised by thetoggle, thereby driving the 'nails from'the die into the work. Thepressure toggles 7 9 aremainta-ined in their straight-line position:until theconclusion of the drivingoperationby reason of the fact thatthe arm 90 is held up by the link 91- during the 'forward'motion of thepitman 39 and therise imparted to the end 62 of-the pitman as the drivertoggle 63, 64 is straightened; The. heel is thus held upon the shoeunderheavy pressure until the attaching nails are driven and clenched. In

.the returnmovement" of the pitman 39 the detent-pin 41 again engagesthe shoulder 42 onthe rod 37 and moves the rod and-the rack 33 rearwardin order to place. the I springs under tension for the next operatiOIk?therefore the endsiof the drivers 72 must beraised to the upper surfaceof the nailing-die. In blind nailing, '0n\thef other 1, 0 In surfacenailin it is necessary to drive a the na ls completey nto the work, and

hand, it is necessary to leave'portions of the nails projecting from thework, and in this case the drivers 72 must not be raised To permit"con--high in the nailing-die. venient adjustment-of the drivers, for thesetwo modes of operation, the driver-block is adjustably mounted on thecross-head, 77. Tothis end it is provided with horizontal lateraltongues 93 engaging corresponding 1 grooves in a block 94. This blockhasin- 'clined lateral tongues 95 engaging corresponding grooves in thecross-head 77,

From the front of the adjusting-block 94 a lug 96 depends, and thislugis connected with the cross-head by of an adjustwardly on thecross-head,"and such'move- :inen't, acting through the inclined tonguesY 102.

During thisad usting movement the relative horizontal position of thenaildrivers'and the nailing-die is preserved, owing to the tongue areintroduced into the die is carried on an arm 104 pivoted at 105 on theframeof the machine.

beingprovided with a pusher 106 which engages a pin 107 on the plate'lOlfor thisr The nails are supplied to the templet 103 I the heel-nailingposition, and for returning 'by any-ordinary or suitable automaticnailfeeding apparatus, and neither this apparatus nor any of theparts-just described isnovel in the present invention.- The meanls forlocking the heel and top-liftcar'rier in it to normal position, are,however, novel; The plate 101 is connected withthe forward bracket. 112.The latch passes freely under and to the rear (.Fig. 6) of thekeepervwhen 'mo 'ing in this direction, but its returnjs prevented, andthus the return movementof the rock-shaft is prevented,until the latchis released at a' suitable time in the operation of the machine. a

To release the latch above described aiid permit the spring 1 l3'to movethe 'heeliand' top-lift carrier intopositi'on to present a top-liftabove the nailing-die, a bracket 121 is clamped upon the rod-22,. andthis bracket hasa horizontal sleeve in which is slidingly mounted a trip122; This trip is normally forced forward by 'a springl23 and itsforward beveled extremity cooperates within beveled head 125 on thelower end of the latch 115. -When t herod 22 moves upward,

during the first part of the operation of the machine, the trip yieldsand idly passes above the head 125, but, after the completion of theheel-nailing operation, when the rod 22 descends the trip pushes thehead 125 downward, thereby withdrawing the latch from engagement withits keeper, and thus releasing the heel and top-lift carrier, so that itreturns to normal position, and this brings a top-lift into position tobe attached to the heel upon the next rotation of f the drive-shaft. I I

In connection with the mechanism for throwing the driving-elutch intooperation,

a safety-device isprovided' toinsure against accidental operation of theclutch; To thisend the rock-shaft 54 has an upwardly.

' end of a rod 108 of which the rear end is ,projecting arm 126 carryingat its" upper Q pivoted to an arm 109' at the upper end of a verticalrock-shaft 111. This rock-shaft is journaled in a bracket 112 fixed tothe rear end with the shaft. This spring tends conof the frame of themachine, and a spring 113 coiled. about-the rock-shaft is connected.

atone end with the bracket and at the other stantly to rock the shaftand the arm 109 in a direction to pull upon the rod 108 and thus toswing the heel and top-lift carrier to the position of Fig. 5, that is,with the top-lift holder above the nailing-die After the heel andtop-lift carrier has been moved, as above described, to bring the heelabove the nail,- in'g-die in position to be secured to the shoe, it isnecessary to retain the carrier in this position againstthe action ofthe spring 113 until the heel has'been nailed: To this end a' lockingdevice is provided for the rock-shaft 111; An arm 114 extends inwardlyfrom the upper end of'the rock-shaft and this arm has a vertical socketin which is slidingly '-mounted a latch 115 provided with a bev eledsurface 116, as shown particularly in This latch is normally pressed up1; ward by aspring 117; VVhenthe parts are moved in opposition to thespring 113 the latch passes under a keeper 118 mounted in an arm 119extending upwardly fromthe end a pin l27adapted to engage a shoulder 128on a horizontal lock-bar'129. The forward end ofthis bar is pivoted tothe toggleis operated, the. rod 132 raises the lock-ban 129,-so as todisengage the shoulder128 from the pin, but afterv the treadleis'freleased, if the spring 55 fails to returnthe clutch arm 55 tooperative position, thevmovement. of the toggle-pin 62 causes thelock-bar .129

to swing the arm 126 rearwardly, thereby turning the rock-shaft andthrowing the arm 55 positively into, engagement with the clutch-lug 56.

Since the automatic adjustmentgof the:

jack compensates, at each operation of'the" machine, .for the varyingthickness offthe work, it is immaterial whether aj heel, or both aheeland a top-lift, be betweenthe jack and the diefat any particularoperation ofthe machine, and for this reason either'" the nailingoperation or the 'top-lift-applying operation may be repeated whenevernecessary, without any manual adjustment 'of-the machine on the part ofthe'operator The use of the. same treadle to controlbotlf the jackadjustment and the nail ng 1111150 Compressing operations simplifies thecontrol of the machine, since it enables the operator to have both handsfree at all times to handle the work andthe nail-templet.
